Click here for more information.
The legislation requires all non-domestic properties to carry out a fire risk assessment and to implement and maintain a fire management plan. For almost all properties this will include the provision and maintenance of a fire alarm system. We supply and fit fire alarm systems in Bath, Devizes, Chippenham, Trowbridge, Swindon, Salisbury, Wiltshire, and South and Central England.
Levels of Cover
Once this consideration has been taken care of, the level of cover to be provided must be determined. Below is an extract from the British Standard to help explain what these levels are and their individual requirements. Hopefully this will help with understanding what is required as well as enabling quotations to be checked for compliance.
British Standard 8.2
c) In Category L3 and L4 systems, smoke detectors, or a mixture of smoke and combustion gas detectors, should be provided in the following: All escape stairways; All corridors; Any other areas that form part of the common escape routes.
d) In Category L3 systems, heat, smoke, combustion gas or multi-sensor detectors should be installed in all rooms that open onto the escape routes described in c), except that rooms opening onto corridors of less than four metres in length need not be protected, provided fire resisting construction, including doors seperate these corridors from any other section of the escape routes.
e) In a Category L2 system, the rooms or areas protected should comply with the recommendations in c) and d) for a Category L3 system, but, in addition, automatic fire detectors should be installed in rooms in which the fire risk is high enough to warrant individual protection.
f) In a Category L1 or P1 system, automatic fire detectors should be installed in all rooms and areas of the building, but the following rooms may not be protected if they are low fire risk: Toilets, shower rooms and bathrooms; stairway and toilet lobbies; small cupboards (typically, less than 1m²); some shallow voids (less than 800mm in depth)
